Subject: Defects Potentially Reportable under 10CFR21
Gentlemen:
We are writing to inform you about a possible material defect in
stainless steel Swagelok tube fittings or adapters. The body of the
fitting in question is stamped with the heat code GNM. It is only the
body of the fitting that is in question.
A list of the U.S. nuclear facilities to which these parts have been sold
is enclosed, along with the relevant part numbers. All of these
facilities have been notified by us about this possible problem.
The type of defect is a strain crack, which occurs during the cold
drawing process. If the geometry on the dies is not set correctly, a
small length of the bar may have an area that can crack. This type of
crack would already be present in the machined fitting, and if not
noticed during installation, would leak immediately upon system
pressurization.
At this time we have only confirmed one fitting from this heat with this
condition.
We enclose a certified material test report from the supplier of the
material, Al Tech Specialty Steel Corporation. The supplier has already
instituted a program of ultrasonically tested stainless steel bars that
we purchase and we believe this would aid in detecting this type of
defect.
We also enclose sales drawings showing the affected parts. All of the
fittings in question are 1/8", 1/4" or 3/8" in size.
